HYDRO CARBON-BURNER.

Specification of Letters Patent.

Application filed March 26, 1915: Serial No. 17,148.

fuel, such as kerosene and other crude oils,

and more particularly to a burner of this kind which is designed for cooking and heating stoves, although it may be used for other purposes, if desired.

One of the objects of my invention is to improve the construction of the air-supplying devices of the burner with a view of in suring perfect combustion and producing a hot and smokeless flame.

A further object is the provision of a simple burner of this class which can be cheaply produced and easily installed.

In the accompanying drawings: Figure 1 is a vertical longitudinal section of the fire box of a cooking stove equipped with the improved burner. Fig. 2 is a horizontal section of the burner on line 22, Fig. 1. Fig. 3 is a transverse central section thereof.

Similar characters of reference indicate corresponding parts in the several views.

1 indicates the fire box of a coal or wood burning stove, which, in the example shown, has an ordinary grate 2.

The improved burner comprises a hollow base 3 resting upon the grate and constructed of suitable dimensions to form a comparatively large air chamber. It is open at its bottom and provided in its closed top with an upwardly-extending mixing tube or collar 4 which opens at its lower end into the hollow base and at its upper end into the fire box. The portion of the grate not occupied or covered by the hollow base is preferably closed by cement 5 or other suitable sealing material to compel the air under the grate to ascend only through the base and its collar 4. Arranged within this collar is the burner proper 6, which preferably consists of the lower horizontal branch of a U-shaped pipe, the upper branch 7 of which is ar ranged directly over the branch 6 and forms a vaporizer for the kerosene or other liquid fuel which is supplied thereto from a tank or other source of supply, not shown. The pipe 7 is provided on the outside of the stove with a valve 8 to regulate or shut off the supply of oil. The burner pipe 6 is provided in its upper side within the collar t with one or more jet openings S fer the oilgas. Directly'above said collar is a suitable flamespreader 9 which in the preferred construe tion shown in. the drawings, is hollow and consists of a circular horizontal chamber 10 interposed in the pipe 7 and forming practi' cally an enlargement thereof. The liquid fuel entering through the pipe 7 is vaporized in a well known manner by contact with the walls of said pipe and the chamber 10, which parts are heated by the flame of the main burner 6, after said pipe and chamber have been preliminarily heated by the customary supplemental burner with which such devices are provided. This supplemental burner forms no part of my invention and may consist of a wick 11 of asbestos or other suitable material seated in a groove 12 formed in the top of the base 3 around the collar 4 and adapted to be saturated with oil or other fuel.

In the construction shown, the burner pipe 6 extends through openings in opposite sides of the mixing collar in which it is clamped by set screws 13 or other appropriate means.

The air ascending into and through the open-bottomed base 3 enters the collar 4 and commingles with the ct of vaporized fuel or oil-gas escaping from the burner pipe, the collar thus forming a mixing chamber, whereby the air is brought into close and intimate contact' with said jet.

As shown in the drawings, the base 3 and collar L are both tapered upwardly. By this construction, the upward air current through the grate is condensed between the up wardly-converging walls of the base and the collar and therefore accelerated, producing an increased draft through said chamber which materially promotes combustion.

It has been found that by the use of this burner the combustion of the vaporized jet is so complete and perfect as to produce a steady, blue and smokeless flame which is intensely hot, rendering the burner especially desirable for ordinary coal and wood burning stoves used for cooking and heating purposes.

While the oval or oblong form of the base 3 shown in the drawings is preferred, the same may be circular or of any other suitable shape, if desired.

As regards the construction of the combined flame spreader and vaporizer, it has Patented Nov. 16, 1915;

1 to said burner-pipe, and a been found that the most satisfactory relargement of the fuel-pipe Which is located Where the heat from the burner is most in-' 'tense,it' is practically impossible for the fuel to pass through said thoroughly vapo *ized. V

The simplicity of the burner renders it inexpensive and enables it to be easily installed, only a single opening in a convenient Wall of the fire-box being required for the entranceof the vaporizing pipe 7.

I claim as my invention:

1. A hydrocarbon burner, comprising an air chamber open at its bottom and provided in its top With an open-ended collar forming a mixing chamber, a burner-pipe arranged in said mixing chamber, a fuel-pipe leading vaporizing champipe Without being Copies of this patent may be obtained for ber of substantially the same diameter as said mixing chamber arranged directly over the latter, said vaporizing chamber forming an enlargement of said fuel-pipe.

2. A hydrocarbon burner, comprising an upWardly-tapering hollow base open at its bottom and forming an air chamber, an upwardly-tapering open-ended collar communicating With the top of said base, a burnerpipe arranged Within said collar, a fuel-pipe leading to the burner-pipe and arranged above the same, and a combined flame spreader and \aporizing chamber arranged directly over said collar and constructed oi substantially the same diameter as the small end thereof, said vaporizing chamber forming an enlargement of said fueLpi 3e.
